Core MechanicRoll d100 without adding a modifier to the roll and succeed at or below the skill's percentage after difficulty adjusts that target. Critical successes fall within one tenth of the adjusted skill, rounded up. Opposed tests compare success levels and break successful ties with the higher roll.Roll a pool of d10s equal to Skill + Attribute. Each die showing 8+ is a hit; 10s count as two hits. Add Enhancement (bonus hits from gear, abilities, or circumstances). Spend hits to meet the difficulty, buy off Complications (side effects attached to the roll), or purchase Tricks (extra effects like knockdown or critical hits). Failed rolls generate Momentum, a shared pool players spend for bonus hits, to turn failures into successes, or to introduce story facts.

Best ForGroups who want to build a science-fiction campaign around a starship crew and competing organizations. Optional extended conflicts give negotiations and chases the same round-by-round attention as fights.Groups who want a genre-agnostic d10 dice pool engine with dedicated subsystems for action, investigation, and social intrigue: especially those building their own setting or adapting existing Storypath games.
HighlightsModular ship construction connects crew space and equipment choices to handling and damage in combat. Extended Conflicts use depleting pools to make withdrawal a meaningful choice during negotiations and chases. Passions turn personal loyalties into skill bonuses and conflicts between competing commitments.Three distinct play modes (action-adventure, investigation, and influence) each with dedicated mechanics. Complications and Tricks give every successful roll narrative texture beyond pass/fail. Momentum turns failed rolls into a shared resource that keeps the story moving. Modular building-block systems (powers, heists, vehicles, crafting, large-scale combat) plug into any game.
ConsiderationsThe core supplies creation tools rather than a ready-made campaign setting or playable adventure. Default combat tracks hit points by body location, and a Major Wound incapacitates immediately and can kill outright on a failed Endurance roll. Starship motion uses an abstract Speed value that mostly ignores conservation of momentum.No included setting beyond three short examples: groups must build or adapt their own world. No free quickstart or SRD available. Multiple interacting subsystems (Enhancement, Advantage, bonds, Complications) take several sessions to internalize.
